Similar reference characters refer to similar parts throughout the views I The apparatus shown in the accompanying drawings comprises, principally, the base A, the copy support plate B, the line indicator mechan'ismC, and thearm D.

The base A comprises the foot 10 and the upwardly extending cover 11 having the bottom thereof secured to the foot 10 by screws or other means. The cross-arm 12 is secured to the upper end of the cover 11, by spot welding, or screws, or by clinching materials, or in any other suitable manner and extends to each side of the cover 11.-

The guide bars 13 and 14, round in the present instance, extend upward from the foot 10 and have the lower ends thereof secured tojthe foot 10 and the .upperends thereof secured to the respective ends of the cross-arm 12.

The plate B has the sides 15 thereof curved to partly encompass the bars 13 and 14 with a clearance therebetween as seen in Figs, 5 and"? and is adapted to slide up and down or vertically in relation to the guide bars.

As best seen in Fig. 5, the rollers 16 are journaled on the pins 17 on the back ofthe plate B, near the bottom thereof. 'Each of the rollers 16 has the groove. 18 in the outer circumferential surface thereof and is spaced so that this groove engages the respective guide bar and thereby guides the lower end of theplate in its vertical movement. v 1 As best seen in 4-, the upper end of each of the bars 13 and 14 is reduced in diameter, the sleeve 19 extends over this reduced end, and the nut 20 is threaded to this reduced end to retain the sleeve 19 in position. Each end of the cross-arm 12 is provided. with the ear-21 extending over this reduced end of the guide bar between one end of the sleeve 19 and the nut 20. The sleeves 19 fit slidably into the curved sides 15 of the plate B and guide the upper-end of this plate in its vertical movement.

The rollers 16 and the sleeves 19 are made of non-metallic material, such as fiber or rubber,-to prevent metal to metal contact between theplate B and the bars 13 and 14 to silence the operation of the plate B.

The rear bracket of the line indicator mechanism C is composed of the bar 22, round in the present instance, extending across the back of the plate B and the ends 23 extending forward of the bar 22. The outer end of each of the ends 23is provided with theboss 24.

The bracket supporting the line indicator mechanism 0 lSTOIlnGCl of sheet metal and comprises the base. 25, the loop 26 encom- I passin a ortion of the bar 22 and the x E J flange 27 superimposed over the base The screws 28 pass through the cover 11 and through the base 25 and through the flange 27. p i

The bar 22 can rotate in the loop 26 and this loop can be adjusted, by manipulation of the screws 28 as is well known in the art,

to create sufficient friction between the loop.

26 and the bar 2 to retain the rear bracket in adjusted position but to permit this rear bracket to be adjusted without manipulating the sci'ews'28. With this arrangement, one pair of screws secures the bracket to the base A and also provides for adjustment of the joint betneen the loop 26 andthe bar 22.

The front bracket of the line indicator mecl'ianism C comprises the bar 29, round in the present instance, and extending across the front of the plate B, and the extends 30 A extending backwiird of the bar 29,-and the journal portions with the bar 29.

As best seen in Fig. 8, each of the bearings 32 has one end thereof secured to the boss 24 and the other end thereof provided with a taper external thread. The journal portions 31 are journaled in the bearings 32 each of which is split longitudinally. The

adjusting nut 33 is provided with an internal taper thread adapted to the external thread on the bearings 32. With this arrangement, the portions 31 can rotate'in the bearings 32 and these bearings can be adjusted, by manipulation of the nuts 33 as is well known in the art, to retain the front bracket in adjusted position but topermit 31 substantially 7 parallel this front bracket to be adjusted without manipulating the nuts 33.

The line bar 34, of the line indicator mechanism C, made of sheet metal in the present instance, has the lower end 35 curved anism C has the rear bracket adjustable on the plate B, and the front bracket adjustable on the rear bracket, and the line bar adjustable on the front bracket. This; ar raugement permits of awide range of adjustment and the adj ustment- .features of the jointsin this indicator mechanism C permits of easy manual adjustment of the line bar and of taking up wear and thereby increases the efficiency of the apparatus and prolongs the life of this mechanism.

The upper end of the plate B is provided with thehorizontal flange 3,6' and the vertical flanges 37 projecting beyond the sides 15. A bracket38 is secured to each of the flanges 37 and each bracket 38 extends abovethe flange 36.

The copy holder comprises the bar 39, the

crank portion 40 on each end of the bar, the

journal portion 41 adjacent each-f these crank portions and journaled in thebracket 38,'and the handle portion 42 provided-With the knob 43. The friction rollers 44 are journaledon the bar 39 to facilitate the re moval of copy sheets fromthe plate hyper- 'initting these rollers to rotate so that the copy holder need not be operated manually When asheet ofvco'py is removed from the iront of the platela'. 1

This copy holder is; forced toward the plate B and also held in inoperative position by the springs 45 one end of which is secured to the crankiportion While the springs retain thefbar 39 in this inopera- Lil (ill

tive position until the bar 39' is moved down Ward manually to oinj'ust beyond the neutral.

plane of both-ends of the springs '.Wl1IB,- uponithese springs forcethe bar 39 toward the plate B and clamp the: copy 47 thereonas best seen in Fig-11.- l I The copy clip comprises the Ibar'48,1-tl.e crank portion 49 on each end-of this bar and looped to form a handle, andthe journal portion 50 adjacent each-of the crank portions and journaled in the bracket 38 on a plane alittlel-ower than the journal's on the copy holder. I j This copy clip is forced-down upon the edge of the flange 36.ai1d;isalso held in' inoperative position by the springs 51-"0116.

end of which is secured to the crank portion '49 while the other send is secured to the bracket 38. The springs lxactand are disposed in a manner snnrlarto the springs 45.

Since the copy 'clip is journaled kin the bracket 38in lowerplane than'the copy holder, the crank portions-'49 abut the crank portions 40 when the bar 48' is; in inoperative position.

The copy clip is nianually'moved toorpast neutral position and either into mop eratiyeorinto operative position similar to the copy holder. .Vhen in operative position. the bar 48 clamps the discarded sheets,-

52 for instance, on the back of the plate B as best seen in Figl'. 11. f

.' It is to be. observed that the arrangement of the copy holder and the copy clip elfece twely holds the copy to the front otthe plate and the discarded sheets 'to the back 7' "the platewhenthese mechanisms are in operative or holding positions and also retains the copy holder and the copy-clip 1n inoperative or releasing positions ahov'e't'l-ieplate and thereby leaves both hands-oftne operator free .to manipulate the copy 'and provides inoreclear space on and around the plate for :suchmanipulation of the copy.

The other end of the aringis secured tolthe plug 62 which has a polygonal opening through which the portion :59. passes. -S-ince the portion 59 is unrotataloly mounted and since the'plugGZ- is unrotatable in relationto the portion 59 theispring 60 is inf and since the 'spring GO has gone end secured to the-shaft: 55. which can rotate and the other en'dsecur-ed to the plng'62 Whichucan not rotate aro'tation ofthe shaft 55' Wind up the ispring The sprocket=63issecured to" the shaft 55 and rotatestherewith! The sprocket 64 is jo'urnaled on thehross-hrnr by of the pin 65 supported in oblong. openings to permit of adjustment- 0f the chain which connects the-sprockets'63 and 64.

The lug GT'issecured tothe hack of the ilate sand projects -backivard sufficiently far .to engage thelinks ofwonefside of the chain '66 is best s een 'in Fig. 11:.

The arm D forms partof the base A, ex-

In order to. provlde adjustment for this journal'- and to prevent. the shaft 55 from moving lengthw1se,.1 split this ournal and provideithe' screw 69 traversing tliisasplit and located so that a portion of the body thereof engages the groove .70 in the shaft 55 to prevent longitudinal rtiovementof the shaft. 'inanipulatio n'of this screw 69 the frictioniof this journal can be adjusted so that theplate B canv be tilted-intodesired position and remain in this position;

'By' journaling one endof the arm. D on the shaft 55;. th a1-m with the lovers thereon can be rotated toe position" alongside of one 7 side of the plate B so that the apparatus can the ears 73 of the foot- 10, that the sides of the knobs 72 extend beyond the ends of the ears 73, that the apparatus rests in the ends of the knobs 72 when the same is in operative position, and that the apparatus rests. on the side of the knobs 72 and on the end of the knob 71 when the apparatus is in inoperative position or folded up.

The cup 74 is screwed onto the shaft adjacent the arm D and the cap 75 is journa-led on the reduced end of the shaft 55 and held in longitudinal position thereon by the nut 76.

The stop bracket 77 is secured to the arm D and extends into the on 74 where it is provided with the bumper 78, of rubber or other cushioning material.

'The block 79 is secured to the inside of the cap 75 at an angle as best seen in Fig. 10 and has the notch 80 and the cushioning bumper 81 anchored therein.

The roller 82 lays loosely between the inner circumferential wall of the cup 75 and the bumper 78 and the block 79.

I The index lever 83 is fulcrumed on the arm D intermediate its ends. Theinner end of the lever83 is provided with the slot 84 to engage the. pin 85 secured to the cap 75.

' The spring 86 normally holds the inner end of the lever 83 down and the adjusting screw 87 is provided to adjust the up and down movement of this inner end of the lever 83 Thehousing 68 is secured to the arm D,v

has the outer wall 88 substantially tangent tothe outer circumferential wall of the cup 74, and also hasthe top wall 89. The roller 90 normally lays between the wall 88 and the outer circumferential wallof the cup 74 due to its own weight; The top wall 89 end of the lever 91 in lowest position.

prevents the roller 90 from leaving the housing 68 when the same is moved upward.

The release lever 91 is fulcrumed on the arm D intermediate its ends. The inner end of'the lever 91 projects through the open ing 92 in the housing 68 belowtheroller 90. The spring 93 normally holds the inner As to operation Due to gravity, the roller 90 norinall contacts the 'wall'88'and the outer circumferential wall of the cup '74 a-nd'theiebywedges itself bet-ween these walls and acts as a brake to prevent the rotationof the shaft 55 in the direction of the arrow shown in Fig. 10 whilein this position although the shaft 55 can rotate freely in the opposite'direction. When the outer end of the the chain 66 engages the lugs 67 to operate theplate B. The plate B is balaneedby manually disengaging the chain link from the lug 67 and manually moving the chain in the direction shown by the arrow in Fig. 11. This movement of thechain rotates the shaft 55 and winds up the spring 60 and is continued until the strength of the spring is equal to the weight of the plate at which stage the chain link nearest the lug 67 is hooked over this lug.

Then different weights of copy are placed on the plate B, the above balancing operation is continued until the strength of the" spring is equal to the combined Weight of the plate and thecopy. i 1 After the apparatus is so balanced, the

, plate remains in any vertical position because the roller acts as a brake and pre vents the-shaft 55 from rotating in the direction which would permit the plate to move downward as long as the release lever 91 is in normal position.

When it is desired to move the plate B upward, the outer end of the lever 83 is pressed down causing the inner endthereof to move upward which movement also moves the. pin 85 upward and rotates the cap 75 on the shaft 55. When the cap so rotates, the block 79 moves therewith and wedges the roller. 82 between the inner circumferential wall of the cup 74 and the block 79, thereby causing the cup 74 and the shaft 55 to rotate as far as the adjusting screw 87 permit-s.

This rotation of the shaft 55 moves the chain 66 and consequently also moves the plate B through the lug 67.

When the pressure on the outer end of the lever 83 is released, the spring 86 returns the lever 83 to original position, thereby 1 0- tating the cap in opposite direction and releasing the block 79 from the roller 82 and permitting the same to drop noiselessly upon the bumper'7 8 to original position. The

block 79 naturally follows the roller 82 in this downward movement and the bumper 81 noiselessly' abuts'the rollei"82:at the end of this movement. Y t

- During the upward movement of the plate B, the spring 60 unwinds but a fairly even balance is maintained due to the'length of the spring. The spring again is'wound up during the downward movement of the late. p When it is desired to move the plate B downward, the outer end of the release lever- 91 is pressed down which movement releases eadset as bra e pretieusiy described and permits plate may be a base, a

the shaft to rotate in either direction, there permitting the plate to move c lownward due to gravity since the spring is now partly uniivou'nd andthe previous, balanced condition has been'disturbed but is again restored as the plate moves a emear c This downward movement of the plate eoauausa's long as the .outerfend of the leyer ,91 is held dawn or until the. plate reaches the' ,1owst positionfat which: stage it abuts neiselessly therubbgerstool 9 1 securedfto the cross-arm 12; The downward movemeatof the plate ,is further cushioned by the spring 60 Winding'up as the plate moves down. I

When it is desired toar'rest the downward movement 6 theplate B at any stage for its tfa-vehit is. only necessary to release the outer end of the lever 91 at that'particular Sta ewhereupon the reuse a0 automatically drops into brake position and arrests further downward moi' em'en't of the plate. Aiiy furthei downward movement of the plate can be i started again pressing down thefouter of the lever 91 and can be terrnniated as just described, Any u ward movement or thepla'te can be; started from my position of the plate by pressin down the outer end ofthe leyer 88,1, f l a v I. am awaiethat es 'y' holding apparatus has been inade with avertieauymovable "su port plate na with me ns; 6151 moving this plate upward and aewawar'a therefore, I do not bl'aii'ii such featurebroadly, but
